HENRY G. SWAN, OF OSHKOSH, \VISCONSIN.

TWO-WHEELED VEHICLE.

SPECIFICATION forming; part of Letters Patent No. 319,037, dated Tune 2, 1885.

Application filed October .17, 1884. (No model.)

To all whom it may concern:

Be it known that I, HENRY G. SWAN, a citizen of the United States, residing in the city of Oshkosh, county of \Vinnebago, State of Visconsin, have invented new and useful Improvements in Hanging the Body and Gear of TwolVheeled Vehicles; and I do hereby declare that the following is a clear, full, and exact description of the same, reference being had to the accompanying drawings, which form a part of this specification.

The chief objections to two-wheeled vehicles are the two disagreeable motions, one commonly called horse motion, which is a succession of quick, sharp movements communicated to body of said two-wheel vehicle from horse by medium of shafts, and the other is the pitching back and forth of body of said two-wheel vehicle when being started or stopped or going in and out of holes in the road.

The object of my invention is to so attach the shafts of said two-wheel vehicle to body and gearing as to completely overcome these above-mentioned two disagreeable motions; and I attain the above object by means of mechanism illustrated in the accompanying drawings, in which- Figure l is a side view of upper portion of two-wheeled vehicle, showing my improvements. Fig. 2 is a half end view of same portion. Fig. 3 is a detached view of my invention in perspective. Fig. 4 is a perspective view of one part of my invention called a lever. Fig. 5 is a perspective view of my invention attached to body and shafts of twowheeled vehicle. Fig. 6 is aperspective view of one part of my invention called a lever and spiral spring.

Similar letters refer to similar parts through out the different views.

This my invention will be more fully illustrated in detail in the accompanying drawings, in which S, Fig. 1, represents body of two-wheel vehicle; 1* shafts, of which there is one on each side of body; D, socket for torsion or spring rod A; B, plate or socket bolted to spring-block F; G, lever; H, rigid support or prop bolted to body, and I I nuts, which adjust the bod y to suit different heights of horses. Fig. 2 is a half end view of same part.

Fig. 3 shows my improvement detached, A A A A being torsion or spring rod; D, socket for holding same rod A, having square holes, into which rod A fits and is keyed tight; E,

shaft, to which socket D is bolted; F, springblock, which supports body on springs; B, socket bolted to spring-block F; C, another socket bolted to inside of shafts E and fitting closely into socket B; G, lever keyed tight in center of torsion or spring rod A, and fastened by means of nuts I I to support or prop H, which is bolted tight to body, as in Fig. 1.

K, Fig. 3, is a spring.

By reference to Fig. 3 it will be seen that the vehicle is drawn by socket C, bolted to shafts E, fitting closely into socket B, bolted to spring-block F, spring-block F being bolted to body S, as in Figs. 1, 2, and 5. Thus no part of the draft comes on the torsion or springrod A, which passes freelythrough sockets 0 and- B and spring-block F. I overcome the quick, sharp succession of movements in shafts commonly called horse motion and prevent its being communicated to the body of vehicle by means of torsion or spring rod A, each end being keyedin socket D, as per Fig. 3, and center of rod A being also keyed solid to lever G. When the above-menti0ned horse motion is produced by action of the horse when moving, it passes to shafts E, and is taken up by torsion or spring rod A, twisting between keyed bearings, and no part or portion of said horse motion is communicated to body of vehicle, which is allowed to'remain level. By reference to Fig. 1 it will be seen that when shafts E are raised slowly at forward end, as in case of using very tall horse, the lever G raises also at end where nuts I I are placed. Pulling up forward end of body to balance body, I raise nuts I I on prop H, which allows body to regain its proper position, and proceed the same way when using small horse. In place of using spring-rod A, I may use a similar rod of non-springing metal and attain the desired result, viz-disposing of the horse motion by means of rubber cushions or m, Fig. ;lor spiral springs]? P, Fig. 6, the adjustment in either case being the same, as in Figs. 1 and 3, by means of nuts I I.

Another feature of my invention is the manner and locality of attaching shafts to body and gearing, and by this device I overcome the second objection to two-wheeled vehicles--na1nely, tendency of the body to pitch forward and back when vehicle is being stopped and started or in passing in and out of uneven places in the road. This will be more fully illustrated by reference to Figs. 1, 5, in which shafts E E, Fig. 5, draw the vehicle, and by attaching body and gear to side shafts, E E, by sockets B C, Fig. 3, the draft comes at a point which is the dead-center of the whole weight of body and gearing, and when shafts E E are moved either backward or forward the whole vehicle must move on a direct line with the shafts without any pitching one way or the other.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination of torsion-spring rod A with sockets B O D and lever G, prop H with 20 HENRY O. SWAN.
